An example embodiment of the present invention and its potential advantages are understood by referring to FIGS. 1 through 7 of the drawings.
FIG. 1 is a diagram of an apparatus 100 in a flat configuration comprising layers 105 and 110 according to an example embodiment of the invention. In an embodiment, an apparatus such as apparatus 100 comprises a flexible hinge. In an embodiment, the hinge is at least one of non-metallic and non-conducting. Further, in an embodiment, the apparatus comprises first and second layers 105 and 110, the first layer 105 comprising an elastomer and the second layer 110 comprising a composite fabric. In an embodiment such as FIG. 1, the apparatus is flat. In an embodiment, such as FIG. 2, the apparatus is at least one of curved and shaped. However, the apparatus may be curved and/or shaped in any way appropriate for a particular hinge application.
In an embodiment, the first layer 105 comprises an elastomer. In an embodiment, an elastomer is any rubbery material such as but not limited to thermoplastics, thermosets, natural rubber, synthetic rubber such as butyl rubber or neoprene and/or the like. In an embodiment, an elastomer is composed of long, chainlike molecules that are capable of recovering their original shape after being stretched. In the embodiment, under normal conditions, the long molecules making up an elastomer material are irregularly coiled. With the application of force, however, the molecules straighten out in the direction in which they are pulled. Upon release, the molecules spontaneously return to their normal compact, random arrangement.
In an embodiment, the first layer 105 comprises a thermoplastic material. In an embodiment, a thermoplastic material is a synthetic plastic or resin capable of softening or fusing when heated and of hardening again when cooled without appreciable change of inherent properties. First layer 105 may comprise any thermoplastic material such as but not limited to polyethylene, polystyrene and/or the like.
In an embodiment, the first layer 105 comprises a thermoset material. In an embodiment, a thermoset or thermosetting material is a polymer-based liquid or powder that becomes permanently solid when heated or cured, placed under pressure, treated with a chemical and/or when treated with radiation. In an embodiment, the curing process creates a chemical that, unlike thermoplastic, prevents the material from being remelted.
In an embodiment, the first layer 105 comprises natural rubber. In an embodiment, natural rubber is a highly elastic solid substance polymerized by the drying and coagulation of the latex or milky juice of rubber trees and plants. Further, in an embodiment, natural rubber does not conduct electricity, readily absorbs mechanical shock and is resistant to moisture.
In an embodiment, the first layer 105 comprises synthetic rubber. In an embodiment, synthetic rubber includes any of several substances similar to natural rubber in properties and uses. Further, in an embodiment, synthetic rubber is produced by the polymerization of an unsaturated hydrocarbon such as butylenes or isoprene. Further, synthetic rubber may be produced by the copolymerization of such hydrocarbons with styrene, butadiene, and/or the like.
In an embodiment, the second layer 110 comprises a composite fabric. In an embodiment, a composite fabric is an engineered fabric made from at least one component such as but not limited to Kevlar®, Cordura®, fiberglass, carbon fiber and/or the like.
